How to evaluate an SEO company before you sign the contract.

An SEO retainer is a bet that a small group of people will improve a measurable set of search outcomes for your business over a multi-year window. You are not buying deliverables. You are buying judgment, and judgment is famously hard to evaluate in a sales conversation.

The framework below is built around that problem. Each question is designed to surface either the firm's reasoning or, more often, the absence of it. The point is not to trip anyone up. The point is to find out whether the team across the table thinks the way you need them to think.

• Walk me through the first thirty days. A serious firm will describe an audit, a baseline measurement, a stakeholder interview, and a prioritized list. A weaker firm will describe a content calendar.
• What is the single biggest mistake you have made on a client engagement? Anyone who cannot answer this has either not been doing the work long enough or is not honest about it.
• Show me the Search Console screenshot from a client win you are proudest of. Real wins have real data. Watch for vague case studies that lean on "traffic up 300 percent" without a denominator.
• Who on your team will actually do the work? The senior partner pitching the deal is rarely the person typing on Monday. Insist on meeting the assigned lead before signing.
• What kinds of clients have you fired? Firms with standards will have a list. Firms without standards will scramble.
• Describe a client you could not help. Honest answers here predict honest answers later when something stalls.
• What is the one thing you would not do for a client even if they asked? Good ethics produce good answers. Vague answers indicate flexible ethics.

Every agency will hand you three reference clients who love them. Those three are not useful. The useful ones are the references you find yourself. Look at the firm's case-study page, identify a former client who is no longer working with them, and call that client cold. Ask why the engagement ended, what worked, and what they wish they had known before signing.

The information density of that single conversation is higher than every sales document the agency will send you. Most buyers skip this step because it feels awkward. Awkward is cheap compared with twelve wasted months.

Most SEO contracts are written by the agency for the agency. A few small changes return the balance of power to the buyer. None of these are unreasonable, and any firm worth hiring will accept them.

• A short initial term. Ninety days, not twelve months. If the work is good, you will renew. If it is not, you have an exit.
• Direct access to Search Console, Google Analytics, and Google Business Profile. You own the data. The agency administers it. Never sign an agreement that puts the property under their account.
• Ownership of all content, code, and links. Anything produced under the engagement belongs to you, including link inventories.
• A clear scope document. What hours go where. How many pages get audited. How many net new pieces of content. Vague scopes produce vague invoices.
• An exit clause that returns your assets. If the relationship ends, all files, content, and reports transfer to you within thirty days.

The presence of any one of these should be enough to walk. The presence of two is malpractice on the buyer's side to keep going.

• Guaranteed rankings. No one can guarantee a ranking on Google. Anyone who does is either lying or about to game the system in a way that gets you penalized. Google's own Search Essentials documentation is explicit on this point.
• Private blog networks or paid links. Any link-building strategy involving networks the agency owns or pays to control violates Google's spam policies and produces medium-term penalties. The penalty outlives the agency engagement.
• Reluctance to give you raw Search Console access. Firms that want to control your view of the data are the firms whose data does not survive being seen.
• An automated tool-generated audit as the first deliverable. Real audits are written by a person. A 200-page Screaming Frog export with no commentary is a sales document.

The honest range for serious SEO retainers in the U.S. market is roughly $3,000 to $15,000 per month for small and mid-sized businesses, depending on competitive market, scope, and the level of executive attention. Anything under $1,500 a month is either junior labor without supervision or it is link spam at scale. Anything over $20,000 a month for a small business is buying expertise you almost certainly do not need yet.

Moz's annual pricing survey remains the most candid public dataset on what real engagements cost. Read it before you take any pitch at face value.

A serious engagement in the first ninety days produces a small set of unglamorous things. A technical audit with prioritized fixes. A list of pages already ranking on the second page of search results that could move to page one with focused work. A keyword strategy tied to actual buyer intent, not vanity volume. A content gap analysis against the top three competitors. A reporting baseline so future months can be measured against something real.

What month three should not produce: a published content calendar of generic blog posts, a "brand awareness" campaign, or a deck about your tone of voice. If those are the early deliverables, the firm is selling you content marketing labeled as SEO. They are different services.

By month six, the technical fixes should be live and showing up in indexing data. By month nine, the content investments should be ranking for their target queries and bringing in measurable organic traffic. By month twelve, the engagement should have produced a defensible answer to one simple question: did organic traffic to revenue-relevant pages grow in a way that pays for the retainer?

That is the only question that matters. Search Engine Land's library on SEO measurement has good primers on building a reporting framework that ties search activity to revenue. Ask your candidate firms which metrics they consider load-bearing and which they consider noise. Their answers will sort the serious operators from the rest.

A great SEO firm will still have months where nothing seems to move. Google updates create temporary chaos. Competitive markets reward patience and punish the impatient. The best evaluation in the world cannot guarantee an outcome. What it can do is make sure the people you hire will think clearly, communicate honestly, and own their mistakes when something goes sideways.

That is the bet you are actually making. Choose the firm that gives you the highest confidence on those three traits and the price almost always sorts itself out.
